In order to improve machinability it is recommended and allowed to adjust sulfur contents from 0.015% up to 0.030%. In relation to weldability it is recommended and allowed to adjust sulfur contents from 0.008% do 0.030%. Maximum 0.015% of sulphur is recommended when polishing is requested.

2

Products carried out from free cutting alloy austenitic steel with high sulfur concentration might be non-compliant with the European Union Directive 94/27 in relation to contact with human skin.

3

If agreed this grade can be delivered with a resistant equivalent to pitting corrosion (PRE = Cr + 3.3 Mo + 16 N) of more then 34

4

Stabilization by titanium, niobium or zirconium extras is allowed. In accordance with the atomic number of those radicals together with carbon and nitrogen contents, equivalence should amount to: Ti =7/4 Ni =7/4Z

C= cold rolled strip; H= hot rolled strip; P= hot rolled plate

2

Advisable values refer to samples: length 80 mm and width 20 mm. It is also allowed to use samples with a length of 50 mm and width 12.5 mm. Only for austenitic steel listed in EN 10088-2, June 2005 and EN 10028-7, January 2000, values refer to transverse direction.

3

Values refer to samples with length 5.65∗√So. Only for austenitic steel listed in EN 10088-2, June 2005 and EN 10028-7, January 2000, values refer to transverse direction.

4

In the case of thickness above 75 mm (for martensitic and austenitic steel) mechanical properties could be agreed

Only for austenitic steel listed in EN 10088-2, June 2005; solution heat treatment can be left out if hot working conditions and subsequent cooling process fulfill requirements specified in EN ISO 3651-2 with respect to mechanical properties and resistance to intergranular corrosion
